  4. Knowledge Base C.reinahrdtii • Autotrophic organism that produces hydrogen in sulfur deprived anaerobic conditions http://www.sciencedaily.com/images/2009/03/090324171556-large.jpg

  5. Knowledge Base Microbial Fuel Cell http://www.gbev.org/images/bio-elektriciteit.jpg

  6. Knoweldge Base Light intensities v. the CO2 exchange when measured by the photosynthetic rate http://generalhorticulture.tamu.edu/lectsupl/Light/p54f1.gif

  7. Literature Review • Rosenbaum, Miriam (2005) ‘Utilizing the Green Alga C.reinhardtii for Microbial Electricity Generation” • Direct electricity generation from microbial photosynthetic activity • Oxidative depletion of hydrogen, photosynthetically produced by C.reinahrdtii under sulfur deprived conditions, by polymer coated electro catalytic electrodes

  8. Literature Review • Melis, Anastasios (2000) “Sustained Photobiological Hydrogen Gas Production upon Reversible Inactivation of oxygen Evolution in C.reinhardtii” • Method circumvents the severe oxygen sensitivity of the reversible hydrogenase by temporarily separating photosynthetic oxygen evolution and carbon dioxide accumulation

  9. Literature Review • Posewitz, Matthew C. (2004) “Hydrogen Photoproduction is Attenuated by Disruption of an Isoamylase Gene in C.reinhardtii” • STA7 is an isoamylase gene in C.reinahrdtii, which is important for starch accumulation and metabolism, which plays an important role in hydrogen photoproduction

  10. Literature Review • Logan, Bruce E. (2006) “Using Algae and other Biomass for Hydrogen Production in a Modified Microbial Fuel Cell” • A small voltage was applied (.25 V) to the algae, which generated pure hydrogen gas at the cathode

  11. Do Ability • C.reinhardtii: Can be grown in the lab as done in previous years • Light Intensities: Different bulbs can be purchased and used in the school lights • Microbial Fuel Cell: A simple fuel cell is owned by the school
